Activities of natural radionuclides 226Ra, 238U in underground brines of Cambrian sedimentary sequence in area of “Udachnaya” kimberlite pipe (Siberian plate) are considered. Activity of radium increases with the degree of the metamorphization of the underground brines. The work is done with the help of high-resolution semiconductor gamma-spectroscopy on state assignment of IGM SB RAS and on the project No. 18-45-140020 «Features of nuclear technogenesis by the example of the object of the peaceful underground nuclear explosion «Crystal» supported by the Russian foundation for basic research.
